Wiring and Serial Plate Amperage
Field Wiring must be sized for component amperes stamped
on the serial plate. Actual ampere draw may be less than
specied. Field wiring from the refrigeration control panel to
the merchandisers is required for refrigeration thermostats.
Case amperes are listed on the wiring diagram, but always
check the serial plate.

Finishing Touches
Bumper Installation Tips
1. Start to attach the bumper at one end of the lineup,
preferably on a straight case.
2. Push the end of the bumper into the bumper
channel rmly. This may be difcult if bumper is cold.
3. Bend the bumper backwards to open and guide it
forward onto the bumper channel.
4. An inside bumper miter must be cut on wedges.
5. Loose ends on miters must be anchored with
screws on the bottom edge.
6. The top and bottom edges of the bumper must be
rmly seated into the retainer by applying with a
rubber mallet (not by hand).
7. The bumper should be struck by the mallet at a
slight angle that forces the bumper back into itself
to prevent stretching. The installation can be made
easier by applying a parafn block to the retainer
grooves.
Installing Splashguard
After merchandisers have been leveled and joined, and
all drip piping, electrical and refrigeration work has been
completed, install the splashguards. Splashguards may
be sealed to the oor using a vinyl cove base trim. The
size of trim needed will depend on how much the oor is
out of level.
NOTE: The splashguard must be removable to allow access to
components behind it.
1. Remove all dirt, wax, debris, etc. from the area of
the splashguard to ensure a secure adhesion.
2. Apply a good contact cement to the trim, allowing a
proper dry time.
3. Install trim to the splashguard so that it is ush with
the oor.
User Information
Stocking
Improper temperature and lighting will cause serious
product loss. Discoloration, dehydration and spoilage
can be controlled with proper use of the equipment and
handling of product. Product temperature should always
be maintained at a constant and proper temperature.
This means that from the time the product is received,
through storage, preparation and display, the temperature
of the product must be controlled to maximize life of the
product. Hussmann cases were not designed to “heat up”
or “cool down” product - but rather to maintain an item’s
proper temperature for maximum shelf life. To achieve the
protection required always:
1. Minimize processing time to avoid damaging
temperature rise to the product. Product should be
at proper temperature.
2. Keep the air in and around the case area free
of foreign gasses and fumes or food will rapidly
deteriorate.
3. Maintain the display merchandisers temperature
controls as outlined in the refrigerator section of this
manual.
4. Do not place any product into these refrigerators
until all controls have been adjusted and they
are operating at the proper temperature. Allow
merchandiser to operate a minimum of six (6) hours
before stocking with any product.
5. When stocking, never allow the product to extend
beyond the recommended load limit. Air discharge
and return air ow must be unobstructed at all times
to provide proper refrigeration.
6. There are vents located at the base of the front
of the glass, just above the front rail. These vents
supply a continuous, gentle ow of air across the
front glass which inhibits condensation. Do not
place any signs or other restrictive objects on the
front of the refrigerator that will block these vents.
